Rare Insight Into The Operations Of The B-52s.
The venerable U.S. Air Force B-52 Buffs have been supporting the air war on ISIS since April 2016. They Stratofortress strategic bombers, based at Al Udeid, Qatar, launched their first air strike against a Daesh weapons storage facility in Iraq on Apr. 18, 2016.
As already highlighted in a previous article, the USAF B-52s have mainly flown Close Air Support and Air Interdiction mainly delivering two types of JDAMs (Joint Direct Attack Munitions): the 500-lb laser-guided GBU-54s and the 2,000-lb GPS-guided GBU-31V3 “bunker busters” loaded onto the Heavy Stores Adaptor Beam pylons.
The typical loadout includes 3x GBU-31s and 8x GBU-54s along with PGMs carried inside the bomb bay of the B-52H Stratofortress. With the 1760 Internal Weapons Bay Upgrade the Buffs can carry up to 16 external laser JDAMs (8 per pylon) as well as 8 internal J-series weapons mounted on a conventional rotary launcher: a mix of PGMs that gives the Buffs the ability to deliver attack both stationary and moving ground targets. In particular, the GBU-54s, that combines 500-lb Mk-82 warhead and the precision strike capability delivered by its dual Laser/GPS mode guidance system can be used against targets with reduced collateral damage.
For hardened targets or concrete shelters, the weapons of choice is the GBU-31s.The JDAM is a GPS aided inertially guided bomb. The Guidance and Control Unit (GCU) containing a HG1700 RLG, GEM-III GPS receiver and computer package is installed inside the bomb tailkit. The GCU is used on the bunker busting 2,000-lb class BLU-109/B forged steel penetrator warhead.
The GBU-31s are assembled at Al Udeid Air Base, Qatar, by airmen from the 379th Expeditionary Maintenance Squadron’s Munitions Flight. Considered that the base
The following video provides a really interesting point of view: it shows a high-altitude attack on a target in western Mosul (according to @obretix), as seen from the cockpit of a B-52 of the 23rd Expeditionary Bomb Squadron on May 23, 2017. The detonation of the bombs as they hit the ground appears to be pretty huge.
